This service returns a, possibly empty, list of those strings that are in one of the input lists but not in both. For example, the input parameters ['a','b','c'] and ['a','e','c'] will return ['b','e']. The input values ['a,'b','c'] and ['a','c','b'] will return an empty list []. Note that the order of elements in the returned list should not be relied upon.
